Gold-filled refers to a type of jewelry material where a thick layer of gold (usually 5% or more by weight) is mechanically bonded to a base metal (such as brass or copper) through heat and pressure.
Unlike gold plating, gold-filled items have a much more durable gold layer, making them more resistant to tarnishing and wear.
Durability – The gold layer is thicker than gold plating, making it last longer (often decades with proper care).
Legal Standards – In the U.S., gold-filled items must contain at least 5% gold by weight (e.g., "14K GF" means 14-karat gold makes up 5% or more of the total weight).
Affordability – Cheaper than solid gold but higher quality than gold-plated items.
Hypoallergenic – Suitable for most people with metal sensitivities (since the base metal is fully covered).
"14K GF" = 14-karat gold-filled
"1/20 12K GF" = 1/20th of the weight is 12K gold
Avoid harsh chemicals (e.g., bleach, chlorine) to preserve the gold layer.
Clean with mild soap and water, then dry gently.
